UPDATE. (Issued 923 PM CDT Tue Sep 29 2020)

First batch of light showers associated with weak mid-level short wave has moved off to the east, but a few more light showers will be affecting the northeast CWA next few hours due to warm air advection ahead of approaching stronger mid-level short wave. This second wave will bring more showers to southern WI late tonight into Wednesday morning. More clouds than clearing are expected during the overnight, so temperatures looking in good shape.

Kavinsky

SHORT TERM. (Issued 353 PM CDT Tue Sep 29 2020)

Tonight through Thursday:

A few showers will swing through through early evening as a shortwave moves through, with some clearing possible later tonight.

Shortwaves will then move through early Wednesday and then again Wednesday night into Thursday, bringing a couple rounds of showers to southern Wisconsin. The best chance for showers tomorrow will be during the morning into early afternoon, with the best chance Thursday during the afternoon. Not out of the question for a rumble or two of thunder both days. Below normal temperatures will continue, with some frost possible Thursday night.

DDV

LONG TERM. (Issued 353 PM CDT Tue Sep 29 2020)

Friday through Tuesday:

High pressure will bring a break to the showery pattern on Friday, with some sunshine even possible. A cool airmass will be in place though, so highs will struggle up to around 50. Frost will be possible again Friday night.

Models are in decent agreement showing a stronger system moving through the area later Saturday into Sunday. This would likely bring higher chances of rain with it along with more clouds and continued below normal temps.

Early next week looks mainly dry with moderating temperatures.

DDV

AVIATION. (Issued 923 PM CDT Tue Sep 29 2020)

A few more light showers will affect the northeast CWA the next few hours. More widespread showers and lower ceilings will affect southern WI late tonight and mostly Wednesday morning. Ceilings may drop to MVFR for a time behind passing cold front later on Wednesday.

MBK

MARINE. (Issued 353 PM CDT Tue Sep 29 2020)

Low pressure will pass by just north of Lake Michigan tonight into Wednesday. Breezy west to northwest winds and scattered showers are expected across the Lake tonight into Wednesday. The strongest winds will likely be from mid-morning Wednesday into mid-evening. A Small Craft Advisory has been issued for this period and gusts could approach gale force across the southern half of the lake.

A strong cold front will then move through the region late Wednesday bringing brisk north to northwesterly winds across the lake through Friday along with more shower chances through Thursday. The colder air moving over the warmer lake waters will bring a potential for waterspouts on Thursday and Friday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
